A team of GRI researchers who have completed surveys of Lake Pend Oreille, the largest lake in Idaho, received thanks from Idaho Governor C.L. "Butch" Otter for their efforts. The research was supported by the Idaho State Department of Agriculture, with assistance from Bonner County. The Aquatic Ecosystem Restoration Foundation was a partner.

At least two members from assistant professor John Madsen's invasive species team were in Idaho at a time from mid-May through mid-September. They used GPS to conduct two grid surveys of the entire lake and to survey smaller sections where they found invasive species before and after chemical or mechanical treatment. The team also took 300 biomass samples that they will analyze to determine the most effective treatment method.

During their time in Idaho, Dr. Madsen was also included on a panel of experts. Members of the expert panel participated in a tour of Pend Oreille Lake and Kootenai River. They also participated in a public information meeting and answered questions from the public.

In his letter, Idaho Governor Otter thanked Dr. Madsen for the survey work and its value to the Idaho Eurasian Watermilfoil Eradication Program. And he wrote, "I also wanted to thank you personally for continuing to assist my staff in developing sound management techniques."

The Governor's letter in its entirety is provided.
